I think this is the biggest problem with crypto that it will never be able to solve. Every year there are millions of dollars lost in crypto due to scams (the "send me crypto and I'll give you money" kind). The instant you have a digital good people can actually buy with crypto and sell for real money, it becomes a money laundering machine.
Like you could get money from ransomware, buy a ton of games on steam, then sell the account to a third party.
This will probably be "solved" by legally exempting stablecoins from nemo dat. Basically stablecoins will be declared clean by law so recipients don't care.
